Front Right Lower Control Arm for Mazda CX-5 2018–2022 OEM KB7W34300F

The control arm, also known as a suspension arm, is an important component of the front suspension system. It connects the wheel hub assembly to the subframe or vehicle body through ball joints and rubber bushings. The control arm helps keep the wheel in position while allowing the suspension to move freely as the vehicle travels over uneven roads.

Over time, the control arm can bend after an impact, its bushings can crack or deteriorate, and the ball joint can develop play after prolonged use. This damage can affect steering control, vehicle stability, and tire wear.

Signs It May Need Inspection or Replacement

• Uneven front tire wear even when tire pressure is maintained correctly.
